Paul hamden along with William Treurniet have shared with the world answers for many of the questions humankind would have for extraterrestrial beings in the event of contact.
Hamden, alleged medium for the Zeta Reticulan alien race, most commonly known as 'The Grays' and a few other alien races, has surrendered the control of his senses and motor functions and offered his body as a sort of temporary vessel to facilitate interactions between humankind and the aforementioned third party.
In a series of documented conversations with these beings, they claim they exist in a physical plane of reality with their own solar system and yet, they can also maintain consciousness while in a self-induced state of energetic/vibrational/etheric/spiritual existence. This higher frequency apparently is not reserved for the grays, but they assure that we can also achieve this state of consciousness as well as 'everything that is', including the other races that Hamden has also interacted with; AND the technology of their own design, those infamous UFOs we've all seen, whether in real life or video.
In this particular conversation, a Zeta explains how their Spacecrafts work:
Our craft are of a nature that are able to support our biological framework. These craft are living entities. Much like a bacteria, they live, breathe, function and create. Each craft is a singular cell, as we are part of the integrated cell (we are keeping this simple). We are able to interact with the craft as "one whole cellular being". This is why there are no doors to the craft, and why there are no windows.
The craft behaves like a single-celled organism so that it is without doors or windows. A bacterium has transporter mechanisms to import and export material across the cell wall. By analogy, the craft may also have a mechanism for moving beings and materials into and out of its interior. Once inside, beings become one with the craft in order to interact with it.
They (the craft) are grown from what was initially a hybrid framework designed by our best technical and scientific beings, so this explains why we have craft who can also "self-heal". The craft are generic, genetically modified structures. Not all craft have individual operators, but as there are certain parts of our DNA replicated, there is one standard craft for beings to use. There are specific craft for specific beings. These beings are utilized to move in different dimensional aspects of the non-physicality of this physical universe.
The Zeta adds that the craft, like all living things, needs sustenance or a source of energy to survive. He says, "There is a basic life force woven into the fabric of the universe. This energetic form, waveform, feeds and nourishes these cellular craft." For the Zeta, the basic life force of the universe is the energy of consciousness. Everything that is and can be experienced is constructed from this fundamental substrate. Clearly, this is the source of the energy required by the craft to function.
Communication with the craft can be telepathic. We are told, "An astral form is needed or thought projection, but realize this, the thought must be of a very specific nature. And there are biological barriers around craft to stop certain energies from penetrating through the 'craft' which we class as a 'being'".
But not all operations require telepathic communication. "If we wish to see outside, not via telepathic methods, we simply compel the side of the cellular structure of the craft to move to a different state. This allows us to see through to a physical dimensional state."
In the interdimensional areas where the physical rules of this universe do not relate, we are able to assimilate to that state by changing cellular form, as a chameleon would change colours; this is how we "physically" move from one place to another. When a craft dematerializes, the occupants "are part of the process, but shielded by the actual craft as well."
THE PROPULSION SYSTEM
The Zeta craft can access the energetic realm to change its location in the physical realm. A Zeta introduces this method of travel using an analogy.
Imagine if you will a single sheet of fabric. Each thread in the fabric is closely related, this is a linear version of a magnetic grid. Now place many layers of fabric together, you now have a three dimensional block of fabric. The threads are interwoven, directional. How does one move from within the vertical structure to the horizontal levels?
In this scenario, the fabric is of a physical nature, but if the fabric is of an energetic nature, then there is a strong matrix of threads between all layers. This means, in a physical universe, a craft can manoeuvre forwards, backwards, diagonally and sideways. The craft are moving on "etheric rails". They are drawn into the craft and used as a "matter of state" propulsion process. These "rails" are of a nature that the craft can move in any direction as it is using the matrix, like a tractor beam. The craft is taken, "pulled", in the direction it wishes to go. Imagine a container of water in a cube form; can a fish swim in any direction? This is the same process. The matrix is a living field.
